virtio-serial-bus needs to treat "virtconsole" devices specially. It uses VirtIOSerialPort member is_console to recognize them. It gets its value via property initialization. Cute hack, except it lets users mess with it: "-device virtconsole,is_console=0" isn't plugged into port 0 as it should. Move the flag to VirtIOSerialPortInfo. Keep the property for backward compatibility; its value has no effect. Signed-off-by: NMarkus Armbruster <armbru@redhat.com> Signed-off-by: NAmit Shah <amit.shah@redhat.com>

The SCSI spec has a quite detailed list of sense codes available. It even mandates the use of specific ones for some failure cases. The current implementation just has one type of generic error which is actually a violation of the spec in certain cases. This patch introduces various predefined sense codes to have the sense code reporting more in line with the spec. On top of Hannes's patch I fixed the reply to REQUEST SENSE commands with DESC=0 and a small (<18) length.

Currently the SCSIRequest structure is abstracted away and cannot accessed directly from the driver. This requires the handler to do a lookup on an abstract 'tag' which identifies the SCSIRequest structure. With this patch the SCSIRequest structure is exposed to the driver. This allows use to use it directly as an argument to the SCSIDeviceInfo callback functions and remove the lookup. A new callback function 'alloc_req' is introduced matching 'free req'; unref'ing to free up resources after use is moved into the scsi_command_complete callbacks. This temporarily introduces a leak of requests that are cancelled, when they are removed from the queue and not from the driver. This is fixed later by introducing scsi_req_cancel. That patch in turn depends on this one, because the argument to scsi_req_cancel is a SCSIRequest.

With the next patch, a device may hold SCSIRequest for an indefinite time. Split a rather big patch, and protect against access errors, by reference counting them. There is some ugliness in scsi_send_command implementation due to the need to unref the request when it fails. This will go away with the next patches, which move the unref'ing to the devices.

There are more operations than a SCSI bus can handle, besides completing commands. One example, which this series will introduce, is cleaning up after a request is cancelled. More long term, a "SCSI bus" can represent the LUNs attached to a target; in this case, while all commands will ultimately reach a logical unit, it is the target who is in charge of answering REPORT LUNs.
